CMOS Low Voltage, 2 Ω SPST NO Switches

The ADG701L/ADG702L are monolithic CMOS SPST switches. These switches are designed using an advanced submicron process that provides low power dissipation yet also offers high switching speed, low on resistance, and low leakage currents. In addition, −3 dB bandwidths greater than 200 MHz can be achieved.

The ADG701L/ADG702L can operate from a single 1.8 V to 5.5 V supply, making it ideal for use in battery-powered instruments and with the new generation of DACs and ADCs from Analog Devices, Inc.

Figure 1 and Figure 2 show that with a logic input of 1, the switch of the ADG701L is closed while the switch of the ADG702L is open. Each switch conducts equally well in both directions when on.

The ADG701L/ADG702L are packaged as 5-lead SOT-23, 6-lead SOT-23, and 8-lead MSOP.

Product Highlights

* 1.8 V to 5.5 V Single-Supply Operation. The ADG701L/ADG702L offer high performance, including low on resistance and fast switching times. The ADG701L/ADG702L are fully specified and guaranteed with 3 V and 5 V supply rails.

* Very Low RON (3 Ω Maximum at 5 V, 5 Ω Maximum at 3 V). At 1.8 V operation, on resistance (RON) is typically 40 Ω over the temperature range.

* On Resistance Flatness, RFLAT(ON) (1 Ω Maximum).

* −3 dB Bandwidth > 200 MHz.

* Low Power Dissipation. CMOS construction ensures low power dissipation.

* Fast tON/tOFF.
